Deprecated functions in fmesher

Description

These functions still attempt to do their job, but will be removed in a future version.

Usage

fm_spTransform(x, ...)

## Default S3 method:
fm_spTransform(x, crs0 = NULL, crs1 = NULL, passthrough = FALSE, ...)

## S3 method for class 'SpatialPoints'
fm_spTransform(x, CRSobj, passthrough = FALSE, ...)

## S3 method for class 'SpatialPointsDataFrame'
fm_spTransform(x, CRSobj, passthrough = FALSE, ...)

fm_has_PROJ6()

fm_as_sp_crs(x, ...)

fm_sp_get_crs(x)

fm_sp2segment(...)

Arguments

x	A sp::Spatial object
...	Potential additional arguments
crs0	The source sp::CRS or inla.CRS object
crs1	The target sp::CRS or inla.CRS object
passthrough	Default is FALSE. Setting to TRUE allows objects with no CRS information to be passed through without transformation.
CRSobj	The target sp::CRS or inla.CRS object

Details

This function is a convenience method to workaround PROJ4/PROJ6 differences, and the lack of a crs extraction method for Spatial objects. For newer code, use fm_crs() instead, that returns crs objects, and use fm_CRS() to extract/construct/convert to old style sp::CRS objects.

Value

A CRS object, or NULL if no valid CRS identified

Functions

• fm_spTransform(): (See fm_transform() instead) Handle transformation of various inla objects according to coordinate reference systems of sp::CRS or INLA::inla.CRS class.

• fm_spTransform(default): The default method handles low level transformation of raw coordinates.

• fm_has_PROJ6(): Old checker for PROJ6.

• fm_as_sp_crs(): Wrapper for fm_CRS() sp::Spatial and sp::CRS objects.

• fm_sp_get_crs(): Wrapper for CRS(projargs) (PROJ4) and CRS(wkt) for sp::Spatial objects.

• fm_sp2segment(): in favour of fm_as_segm()
